1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

We discuss an extremely rare case of low-grade Schwann cell leptomeningeal neoplasm with no evident intradural primary, presenting with rapid neurological decline leading to death reflecting the aggressive biological behaviour of this entity despite its low-grade morphology. Notwithstanding extensive investigations, the diagnosis was only established on autopsy as clinical presentation is non-specific making diagnosis challenging. This condition could be considered in patients presenting with leptomeningeal disease if initial workup of more common causes is non-revealing.
